Not only is the Triple Thick Shake the only drink bad enough for you that it merited inclusion in the top five worst foods at McDonald's, but it's worse for you than just about anything else they offer. If you wanted to recreate the artery and waistline pounding excess of a large Triple Thick Shake, you'd pretty much have to take a stick of butter, pour 80 Pixie Stix on it, and hit it with a salt shaker before eating the mountain in front of you with a spoon. The small fry is included for a sense of scale both on the physical and caloric level—the fry has 1/5th the calories. Return to Best and Worst Fast Food: McDonald's Edition

The Double Quarter Pounder with Cheese is a burger that doesn't fail to deliver. It delivers the highest calorie, fat, and sodium content of any sandwich or burger at McDonald's. Unless you're purposely selecting your burger based on the amount of collateral damage it can cause, there are other items on the menu with enough flavor to justify skipping this one.

Chicken Selects are deceptive: It's chicken! Compared to the greasy burgers it must be healthy, right? Once you add in the breading and the fat that holds it all together, the Chicken Selects end up little but a distant cousin of the healthy chicken you might grill up at home. Despite the premium label and the illusion of health the chicken label lends them, ordering plain old Chicken McNuggets are better for you. Return to Best and Worst Fast Food: McDonald's Edition

The Grilled Chicken sandwich is an even more deceptive relative of the Chicken Selects. Most health conscious people would order grilled chicken over a burger any day. This sandwich, however, has even more calories and sodium than a Big Mac. If you looked at the Big Mac and forced yourself with steely will to order something healthier but ended up getting this, you got duped and didn't even get the satisfaction of the Big Mac's special sauce.

Big Mac - 540 Calories - 29g of fat (10g sat) - 1040mg sodium

By far the healthiest option—which doesn't say much—among the unhealthy McDonald's items featured here, the iconic Big Mac arguably offers the most flavor with the least damage. If you're going to eat from the worst choices menu, the size of the Big Mac and the tangy special sauce at least make it a flavorful caloric splurge in comparison to the bigger-is-better Double Quarter Pounder with Cheese.
